Hello. I am trying to use a PIT interrupt. I had never used Kinetis so there are certain things which with I am not familiarized yet. once i have created de PE code, cleaned and then I build the proyect, the following error pops up 'undefined reference to int_disp'.

What it is about? Where should I write my ISR fuction? Does the ISR pit function has to have an specific name so as to be recognised by PIT.c?
